, economic value
is a measure of the benefit provided by a good
to an economic agent
. It is generally measured relative to units of currency
, and the interpretation is therefore "what is the maximum amount of money a specific actor is willing and able to pay
for the good or service"?
Among the competing schools of economic theory there are differing theories of value
Economic value is not
the same as market price
, nor is economic value the same thing as market value
. If a consumer
is willing to buy a good, it implies that the customer places a higher value on the good than the market price. The difference between the value to the consumer and the market price is called "consumer surplus
It is easy to see situations where the actual value is considerably larger than the market price: purchase of drinking water is one example.
The economic value of a good or service has puzzled economists since the beginning of the discipline. First, economists tried to estimate the value of a good to an individual alone, and extend that definition to goods that can be exchanged. From this analysis came the concepts value in use
and value in exchange.
Value is linked to price
through the mechanism of exchange
. When an economist observes an exchange, two important value functions are revealed: those of the buyer and seller. Just as the buyer reveals what he is willing to pay for a certain amount of a good, so too does the seller reveal what it costs him to give up the good.
Additional information about market value is obtained by the rate at which transactions occur, telling observers the extent to which the purchase of the good has value over time.
Said another way, value is how much a desired object or condition is worth relative to other objects or conditions. Economic values are expressed as "how much" of one desirable condition or commodity will, or would be given up
in exchange for some other desired condition or commodity. Among the competing schools of economic theory there are differing metrics for value assessment and the metrics are the subject of a theory of value
. Value theories are a large part of the differences and disagreements between the various schools of economic theory.
In neoclassical economics
, the value of an object or service is often seen as nothing but the price it would bring in an open and competitive market. This is determined primarily by the demand for the object relative to supply
in a perfectly competitive market
. Many neoclassical economic theories equate the value of a commodity with its price, whether the market is competitive or not. As such, everything is seen as a commodity and if there is no market to set a price then there is no economic value.
In classical economics
, the value of an object or condition is the amount of discomfort/labor saved through the consumption or use of an object or condition (Labor Theory of Value)
. Though exchange value
is recognized, economic value
is not, in theory, dependent on the existence of a market and price and value are not seen as equal. This is complicated, however, by the efforts of classical economists to connect price and labor value. Karl Marx
, for one, saw exchange value as the "form of appearance" [Erscheinungsform
] of value, which implies that, although value is separate from exchange value, it is meaningless without the act of exchange, i.e., without a market.
"The value of a thing in any given time and place", according to Henry George
, "is the largest amount of exertion that anyone will render in exchange for it. But as men always seek to gratify their desires with the least exertion this is the lowest amount for which a similar thing can otherwise be obtained."
In another classical tradition, Marx distinguished between the "value in use" (use-value
, what a commodity provides to its buyer), labor cost which he calls "value" (the socially-necessary labour time
it embodies), and "exchange value
" (how much labor-time the sale of the commodity can claim, Smith's "labor commanded" value). By most interpretations of his labor theory of value
, Marx, like Ricardo, developed a "labor theory of price" where the point of analyzing value was to allow the calculation of relative prices
see values as part of his sociopolitical interpretation and critique of capitalism and other societies, and deny that it was intended to serve as a category of economics. According to a third interpretation, Marx aimed for a theory of the dynamics of price formation but did not complete it.
In 1860, John Ruskin
published a critique of the economic concept of value from a moral point of view. He entitled the volume Unto This Last
, and his central point was this: "It is impossible to conclude, of any given mass of acquired wealth, merely by the fact of its existence, whether it signifies good or evil to the nation in the midst of which it exists. Its real value depends on the moral sign attached to it, just as strictly as that of a mathematical quantity depends on the algebraic sign attached to it. Any given accumulation of commercial wealth may be indicative, on the one hand, of faithful industries, progressive energies, and productive ingenuities: or, on the other, it may be indicative of mortal luxury, merciless tyranny, ruinous chicanery." Gandhi
was greatly inspired by Ruskin's book and published a paraphrase of it in 1908.[non sequitur]
Economists such as Ludwig von Mises
asserted that "value" is a subjective judgment. Prices can only be determined by taking these subjective judgments into account, and that this is done through the price mechanism in the market. Thus, it was false to say that the economic value of a good was equal to what it cost to produce or to its current replacement cost.
denied value theory
in economics. He thought that value theory is useless and prevents economics from becoming science and that a currency administration guided by value theory is doomed to sterility and inactivity.
The theory of value is closely related to that of allocative efficiency
, the quality by which firms produce those goods and services most valued by society. The market value of a machine part, for example, will depend upon a variety of objective facts involving its efficiency versus the efficiency of other types of part or other types of machine to make the kind of products that consumers will value in turn. In such a case, market value has both objective and subjective components.
, often referred to as the "Three Es", may be used as complementary factors contributing to an assessment of the value for money
provided by a purchase, project or activity. The UK National Audit Office
uses the following summaries to explain the meaning of each term:
- Economy: minimising the cost of resources used or required (inputs) – spending less;
- Efficiency: the relationship between the output from goods or services and the resources to produce them – spending well; and
- Effectiveness: the relationship between the intended and actual results of public spending (outcomes) – spending wisely.
